SCREEN ATTACHMENT.

Specification of Letters Patent.

Patented Mar.. 9, i915.

Application led May 2, 1914. Serial No. 835,916.

To all whom it may concern.'

Be it known that I, WILLIAM S. SIMoNs, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented new and useful lmprovements in Screen Attachments, of which the following is a specification.

This invention relates to window and door screen attachments and the principal object of the invention is to provide a simple and eiiicient attachment which permits the escape of flies and other insects which collect upon the inner side of the screen but which prevents the entrance of the flies into the room.

A further object of the invention is in the provision of a device of this character constructed so that it may be adjusted to any type of door or window screen and adjustable so that it may be applied to screens of dierent sizes.

Further objects of the invention will appear as the following description is read in connection with the accompanying drawing, which forms a part of this application, and in which Figure l is a perspective view showing the screen attached to a door. Fig. 2 is a vertical sectional view taken on the line 2 2 of Fig. l. Fig. 3 is a similar section taken on the line 3-3 of Fig. l. Fig. 4; is a sectional view showing a modification.

Referring more particularly to the drawing, l and 2 represent the separate sections of the device, each being constructed of converging side members 3 and l which are connected together at one end by the end members 5. The sides 3 and Ll have alined flanges 6 arranged along their outer side edges and the end members are provided with iianges 7 having apertures to receive fastening devices whereby the structure may be connected to the window or door screen frame. The flanges 6 are preferably bent to produce a channel 8 which receives the edge of the screen wire 9 thereby preventing the exposure of any ragged edges. The side members 3 and 4@ have the inner marginal edges thereof arranged in parallelism and separated a suflicient distance to permit the exit of a fly through the opening l0 which is designed by outwardly turned lips 1l extending the full length of each and forming guides so that one section will operate over the other, as will be readily understood.

opies of this patent may be obtained for five cents each, by addressing the Gommissioner The sections are connected together adjust ably by oppositely extending clips 12 and 13 which are bent up from the sections 1 and 2 at the side edges of the device and adjacent opposite sides of the opening l0. The clips on one section loosely engage the flanges or lips on the other section so as to permit ready adjustment of the sections for accommodating the device to windows or doors of different width.

In the modification shown in Fig. 4f, the lid of the side 4 is provided with a flange 14 which overhangs the opening l0, as shown, which prevents mosquitos, flies or other insects from flying directly into the room through the opening l0.

In applying the device to a window or door screen the screen fabric is cut away adjacent the top and the sections l and 2 adjusted to the width of the frame. The iianges 7 are secured to the frame and if found necessary the upper iange of the side members -Lt are secured to the frame. The lower flange 6 of the sides 3 has the fabric secured within the channel 8 by clamping the walls of the channel upon the fabric.

lVhat is claimed is l. An attachment for screens comprising a pair of adjustably connected sections each substantially if-shaped in cross section, said sections having alined exit openings at the apex of the t/-oppositely extending lips on opposite sides of the opening, means for attaching the device to a screen frame, and means for attaching one edge of the device to the screen fabric which conceals the rag` ged edge of the fabric.

2. An attachment for screens consisting of a pair of adjustably connected sections, each section comprising converging side members and an end member, said side members terminating short of the convergence point to provide an eXit opening and being provided on opposite sides of the opening with oppositely extending lips, means for connesting the sections to the frame, and a clamping flange carried by each section and adapted to connect with the screen fabric and to conceal the raw edge thereof.

In testimony whereof my signature in presence of two witnesses.
